Specification of Letters Patent.

Application filed February 7, 1910.

Patented Dec. 2?, 1910.

Serial No. 542,391.

To all whom it may concern:

Be it known that 1, JOHN A. Knny, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Portable Wiring Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a portable wiring device for the use of electricians and others in stretching and holding wires in a taut manner until they can be permanently secured by the usual cleats or binding posts.

The objects of the invention are to provide a cheap, durable and effective device of this class, that is dismountable to facilitate transporting with the usual kit of tools, and which may be quickly assembled and set up for use in any part of a room without having to be attached by any means, other than itself.

The device is so constructed that it can be instantly adapted for any height of ceiling, and will stretch and retain two parallel rows of wires at the same time, and at the proper distance from the ceiling or beam face to accommodate the binding cleats.

l/Vith these and other objects in view my invention consists in certain construction and combination of parts as will hereinafter be fully described and claimed and illustrated in the accompanying drawings, which form a part of this application, and in which like figures of reference refer to corresponding parts in all of the views; but it is fully understood that while I have here described my invention as here shown, that I do not confine myself to the exact construction as shown, as slight changes may be made in the construction and arrangement of the several parts without departing from the spirit of the invention.

In the drawings :Figure 1, is a side elevation of the device shown in operation. Fig. 2, is a back elevation of the same, with the body portion removed. Fig. 3, is a top plan view of the same. Fig. f, is a side elevation of the same, with one of the pulleys removed to show the gripping arm. Fig. 5, is a bottom plan view of the telescoping tubular body and adjustment securing means.

Referring to the drawings :the device comprises a head member 1, which is se- I cured upon the upper end of a telescoping body or supporting member which comprises the outer tube 2, to which the head 1, is attached and the inner tube 3, which is formed at its lower end with the floor gripping point t; while said inner tube 3, is retained by and within the outer tube by the clamp 5, which compresses the slotted end of the outer tube 2, thereon. The head memher 1, is formed with a wedge-shaped top 6, for gripping the ceiling by frictional contact therewith; while said head is further supplied with the transverse shaft 7, and the studs 8.

Rotatably mounted upon the ends of the shaft 7, are the sheave wheels or pulleys 9, and which are retained thereon by the pins 10, or other retaining device. Between the wheels 9, and the head 1, and upon the studs 8, are pivoted the gripping arms 11, which are formed with the dog 12, upon the upper end thereof, which is adapted to enter the groove of the wheel 9, and grip the wire 13, therein; while the lower end of said gripping arm 1 1, is formed with a slotted eye 1'" for the reception of the wire 13.

The operation of the device is so simple and will be so readily understood from the foregoing description taken in connection with the drawings, that further details are deemed useless.

Having thus described my invention What I claim as new and desire to secure by Letters Patent is 1. In a device of the class described, a telescoping standard. formed with a lower gripping end, a head secured upon the upper end of said standard, a wedge-shaped top formed upon said head, pulleys mounted upon the opposite sides of said head, frictional gripping arms mounted upon said head adjacent to said pulley and adapted to coiiperate with said pulleys for gripping the wire.

2. In a wiring device of the class described, comprising a telescoping standard, a gripping surface formed upon the lower end thereof, and a wedge-shaped surface secured upon the upper end thereof, grooved pulleys rotatably mounted near the upper end thereof, a double armed lever mounted adjacent to said pulley, a gripping dog formed upon one of said arms and adapted to form a gripping contact within the groove of said pulley, and a wire guide eye formed upon the other arm and adapted to guide relation to said Wheels and adapted to press the Wire and control the gripplng and rea Wire WltlllIl the grooves of said Wheels leasing of said dog. and retain said Wheels from rotating by 3.
